EXTENSION-TABLE.

Specification of Letters Patent.

Patented July 6, 1915.

Application filed October 29, 1914. Serial No. 869,274.

To all whom it may concern:

Be it known that we, HELGIE O. SoHoLD and ANTON A. SwnNsoN, citizens of the United States, and residents of Muskegon, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specication.

This invention relates to tables, as for dining rooms, and the like, and the main object thereof is to provide such a table having self-contained reserve leaves and means for moving a desired number thereof into and out of operative position.

' A further obj ect is to provide means moving said leaves individually and successively into and out of operative position.

A further object is to provide leaves having the sectional continuations of the apron depending from the top of the table, as means for concealment of the table frame and for ornamentation.

A further object is to form each leaf into three parts, one central and two end members.

A further object is to provide a movable element which operates all of said leaves successively, in either direction of leaf movement.

A further object is to provide manually operable devices for actuating said leaves.

A further object is to provide means whereby said manual means may be moved out of sight when not in use; and further objects are to provide such tables which are comparatively inexpensive, simple in construction and use, formed of relatively few parts which are not likely to get out of order to require repair, and which do not deface the normal appearance of the table in either of its positions.

Our invention is fully described in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views, and in which Figure 1 is a top plan view of a table constructed in accordance with our present preferred form, in a two leaf extended position, the leaves being omitted to illustrate details; Fig. 2 is an enlarged section taken on the line 2`2 of Fig. 1, with the table in closed position and having three leaves concealed therein; Fig. 3 is a similar view with the table in a three leaf extended position; Fig. 4 is an enlarged, partial, section on the line 4-4 of Fig. 1, with the table in eX- tended position to show a leaf in position for use; Fig. 5 is a similar view with the table in uneXtended position, and showing the three sections of a leaf therein; Fig. 6 is a perspective view of the main or central part of one of our leaves; Fig. 7 is an enlarged, perspective, view of the leaf operating means; and Fig. 3 is a perspective view of a crank-arm which we employ.

In the drawings forming a part of this application we have shown a table comprising two sections 10 and 11, of which the former consists of an end beam 12, Figs. 2 and 3, side-rails 13 and 14, interiorly channeled, as shown in Figs. 4 and 5, and a center-rail 15 having beveled edges, a transverse plate 16 for supporting two legs 17 while a central leg 18 is supported on the centerrail 15, and we also provide four transverse plates 19, 20, 21 and 22, Figs. 2 and 3, secured to the rails 13, 14 and 15, and the side rails also supportthe table top of this section, shown at 23, and from which depends the apron 24.

The section 11 consists of an end beam 25 and side-rails 26 and 27 slidable in the side'- rails 13 and 14, respectively, as shown in Figs. 4 and 5, a center-rail 28, a transverse plate 29 for supporting the legs 30, a section 31 of the table top, and an apron 32 dependent therefrom, and it will be seen that substantially all of the structure so far described is of conventional form and permits the two sections to be moved apart or together at will.

By reference to Figs. 1 to 5, inclusive, it will be seen that we provide two transversely movable slides 33, grooved on their edges, and held by such grooves upon the plates 19 and 20, each of said slides having' a toggle lever 34 pivoted thereto, at 3 5, and in turn pivoted to the plate 20, adjacent the center thereof, each of said levers having a cam face 36 and an arm 37, the last named pivotal point being designated 38. Slidable transversely ofthe table, on the plates 20 and 21, are two slides 39, similar to those described, having, each, a toggle lever 40 pivoted thereto at 41 and 1n turn pivoted to the plate 21 at 42, each of said levers having a cam face 43 and an arm 44, and. it will be seen that when either of said levers is moved upon its pivot, 38 or 42, the corresponding slide is moved accordingly.

The slides 33 carry, each, an outwardly directed rod 45 pivoted thereto and to a section of table apron 46, at 47, and which section of apron is secured to a section of leaf 48 having a block 49 on the inner side thereof in turn hinged to the side-rails 13 and 14, as shown at 50, and said leaf sections arekmade of a length permitting their normal position below the table top section 31, and within the apron 32, as clearly shown in Fig. 5, and it will be seen that, in the movement of the slides 33, the leaf ends are correspondingly moved.

The slides 39 carry, each, an outwardly directed rod 51 pivoted thereto and to a section of table apron 52, at 53, and which apron section is secured to a section of leaf 54 having a block 55 on the inner side thereof, and also hinged to the side-rails 13 and 14, and. it will be seen that when the slides 39 are moved, the leaf sections are correspondingly moved which are connected therewith.

Secured to each of the side-rails 26 and 27 lis a rack-bar 56, and with each of which a spur-gear 57v is engaged, said gears being revoluble with a shaft 58 carried in hangers 59 secured to longitudinally arranged strips 60 secured above the plates 19, 20, 21 and 22, said shaft having a crank-arm 61 in operative connection therewith, either detachably or, as shown in Fig. 8, being pivoted to the shaft 58 at 62 whereby said crank-arm may be swung out of the way when not in use, and we prefer to employ a sliding sleeve 63 whereby said crank-arm may be maintained in operative position, when desired.

rlhe strips 60 are each vertically grooved in the positions of each leaf, as shown at 64, Fig. 1, and we arrange our central leaf members on said strips, as shown in Fig. 5, said central leaf members being shown at 65, 66, and 67 and each of them is provided with a dependent wedge 68 adjacent each end and which wedges rest in and are guided by the corresponding grooves 64, and the said wedges are each slotted to permit a free movement of the rods 45 and 51, as shown at 69.

Rotatable in and arranged transversely of the center-rail 28 are two spaced rods 70 and 7l, hooked at their ends as shown in Figs. 4 and 7, in such positions as to engage kcorresponding toggle levers 34 and 40 in the passage of said hooks thereover, the former of said rods having a pin therein, at 72, preventing said rod from rotating in one direcsaid center-rail for said pins 72 and 73 to y impinge on.

Assuming the table to be in the unextended position as shown in Figs. 2 and 5, the table top sections 23 and 31 touch each other,`the central leaf sections 65, 66, and

67, are in a plane beneath the table top, and the leaf ends are all in a lowered position on their hinges, as clearly shown in Fig. 5, ready for table extension of one or more leaves.

By reference to Fig. 1 a clear understanding of the operation may be had and, for such clearness we will first force the members thereof yinto unextended position, slowly, having reference to the movements of the various parts, but it must be understood that the center leaf sections 65, 66, and 67 are not shown inthis figure, in order to illustrate the plan view of the operative parts, and it is stated at this time that the plan shown in Fig. 1 is only adapted for two extension leaves, while three are shown in Figs. 2 and 3, this being to make it clear that any desired number of leaves may be arranged in a table, the operative parts now to be described in action being merely duplicated for each additional leaf.

Assuming the table section 10 to be held motionless and the section 11 moved slowly toward itz-The side-rails 26 and 27 slide freely in the side-rails 13 and 14, respectively, as does also the center-rail 28 over the center-rail l5, and this movement of the center-rail 28 carries with it the two rods 70 and 71, the positions of the pins 72 on the former preventing its rotation if an obstacle should be met, whereas the pins 73 on the latter permit its rotation in this direction of movement of the center-rail 28. ln such forward movement the hooked ends of the rod engage the toggle-levers 34 at a point adjacent the cam faces 36 and deflect the same on their pivots, gradually carrying the arms 37 into a transverse position, as shown with reference to the arms 44 of the toggle-levers 40, the hooked ends of the rod 70 sliding over the cam faces 36 until such position of the toggle-levers 34 has been reached, and this movement of the togglelevers 34 carries the slides 33 inwardly until they are in line with the slides 39, their innermost positions.

By reference to Figs. 4 and 5, it will be seen that, in the inward movement of the slides 33, the center leaf section 65 is permitted to move downward as the slides 33 recede from beneath the wedges 68 thereof until the table top section 31 may pass thereover, and the slides 33 also move the leaf apron sections 46 inwardly on their hinges 5() until said apron sections are horizontal, thus carrying the leaf end sections 48 into vertical positions to permit the table top section 31 to pass thereover and, in this direction of movement, the hooked rod 71 rotates freely and produces no result on any of the table parts encountered; this forward movement into uneXtended table position is repeated for each and all of the leaves employed, as the construction and operation of the leaves and of their operative parts are identical, and it will thus be seen that, in this movement, the center leaf sections are successively permitted to drop into lowermost positions, and the leaf end sections are successively carried downwardly out of the way of the advancing table top section 31 until it touches the table top section 23, and the table is in normal or uneXtended positionl `When the table is in this postion, all the toggle-levers are in the positions of those 40 in Fig. 1, and it will be remembered that the rod 70 may not rotate in the movement of table sections 10 and 11 toward each other, but the rod 71 may rotate in this direction of movement, the rod 70, however, being free to rotate in the movement of table sections away from each other, whereas the rod 71 is not free to do so.

When the table section 11 is moved away from the section 10 the hooks on the rod 71 engage, first, the arms 37 of the toggle-levers 34 and move said toggle-levers on their fixed pivots 88, thus moving the slides 33 outwardly and, thereby, moving the leaf section into the plane of the table top and the leaf ends are moved on their hinges until the leaf end top sections 48 are in the plane of the table top, and this leaf is complete; the hooked rod 71 next engages the togglelevers 40 and forces the slides 39 outwardly, thereby carrying the center leaf section 66 into the plane of the table top, as well as the leaf end top sections 54, and this leaf is in position, and this leaf actuation continues, successively, for all of the leaves employed, the moment of leaf actuation being gaged so as to prevent interference therebetween but still allowing the proper movement thereof into operative positions.

llt will thus be seen that the leaves are successively moved into or out of operative positions; that said leaves are each formed of a center section and two end sections independently operable, though simultaneously; that the usual apron of a table is preserved, regardless of the number of leaves employed; that all the parts are self-contained within the table and portable therewith; that said parts are all concealed from View when not in use; that the leaf members do not disiigure the table in any way when in use; that any desired number of leaves may be employed; that only one leaf actuating reduced if not entirely removed; and that a comparatively inexpensive extension table results.

Attention is directed to the fact that we lhave employed the reference characters for both the leaf members 65 and 66 in Fig. 4, as the parts are identical, and the description of either may be equally as well read on said figure, the section line 4-4 not being directly through the table, said Fig. 4 being, rather, a composite section on the lines 4 -4 and X-X, to avoid unnecessary repetition.

Our invention is thoroughly practical and, while we have shown certain specific details of construction, we do not wish to limit ourselves thereto, but may make alterations therein, within the scope of the following claims, without departing from the spirit of our invention, or sacrificing its advantages.

Having fully described the invention, what we claim as new, and desire to secure by Letters Patent, is
